A precision metering device for corn breeding experiment

Abstract

The invention discloses a precision seed metering device for corn breeding test, and belongs to the technical field of agricultural machinery. The precision seed metering device comprises a moving assembly, a lifting assembly, a discharging assembly and a seeding assembly, wherein the moving assembly comprises a vehicle board, a push rod arranged at the front end of the top of the vehicle board and four moving wheels distributed in a rectangular shape at the bottom of the vehicle board; the discharging assembly comprises a mounting frame, a storage box, a closing member and a conveying member;a discharging cylinder communicated with the storage box is arranged at the bottom of the storage box; the closing member is arranged on the discharging cylinder; the conveying member is arranged atthe top of the vehicle board; the seeding assembly comprises a seeding member, a dust removing member and a dust collecting member; the seeding member is arranged on the lifting assembly; the dust removing member is arranged on the seeding member; and one end of the dust collecting member is arranged on the seeding member. After the seeding operation, the dust removing device performs the dust removing operation on the seeding member, and after the dust removing, the dust is sucked away by the dust collecting member, thereby realizing the dust cleaning in a seeding box, and facilitating the next seeding operation of corn.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a precision metering device used for corn breeding experiments. Background technique [0002] Maize mechanized precision sowing can save artificial thinning, save seeds, increase production and save costs, so it has become the development trend of corn sowing in recent years. The seed metering device with stable performance and high-speed operation has become the key to realize the mechanized precision sowing of corn. [0003] For example, the patent with the publication number CN207167024U relates to a clearable mechanical precision metering device for corn breeding field trials, including a base assembly, which also includes a seeding disc assembly, an electromagnet assembly, a rotating shaft assembly and a side wall assembly; the base assembly includes a base, a seed drop port, a base clamping plate and a seed cleaning port, the center of the base is provided w...
